Application filed June 2, 1924. Serial No. 717,415.

' To all fr0/tom t may concern.:

Be it known that I, TALBnI-rr 7. BLAKES- ninna citizen of the United States, residing at Erie:in the county of Erie and State of Pennsylvania., have invented new and useful Improvements in Syringes, of which the following is a specification. j

. An object of the invention is` the provision of a vaginal syringe having `an infiuent and an etlluent tube, so that the outflowing fluid cannot mix with the injected Huid and which is of such construction that the injected fluid will be positively and properly directed to the portion; of the organ desired to be treated, the `effluent tube having associated with the outer portion `thereof a soft elastic hollow substantially Vcone-shaped tube which is also attached to the base of the syringe and vwhich serves as an occluding plug for the orifice of the organ so that the garments of the patient or bed clothing will not be soiled by the outflowing fluid.

A further object` is the production of Vavaginal syringe having an entrance end or nozzle of a particular and peculiar construction for injecting the fluid in a whirling spray and in which the parts constituting the improvement are separately connected, so that different sized parts may be einj'iloyed to suit varying conditions and also whereby the metal parts may be thoroughly sterilized by immersion in boiling water and the occluding tube easily cleaned.

Tov the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawing Figure 1 is an approximately central longitudinal sectional view through my improvement.

Figure 2 is a sectional view on the line 2--2 of Figure 1..

Figure 3 is a sectional view on the line ifi-3 of Figure 1.

The base 1 of the improvement is in the nature of a cup-shaped member having its outer edge beaded, as at 2. The base is of metal and is centrally formed with an an nular depression which is surrounded by a round boss Screwed through the boss 3 there is a nipple 4, and to this nipple is connected the bulb 5.

Screwed in the inner end of the nipple l there is thi` influent tube 6. The tube is also constructed of metal.

vArranged to surround the tube 6, and to be received in the depression surrounded by the boss 3, and arranged in contacting engagement with the said boss thereis the effluent tube S. The tube 8 is of a greater length than the tube 6. The tube 8 is pro-` vided, throughout its length, with a plurality of radially arranged openings 9.

Screwed on the outer end of the influent tube 8 there is the entrance end or nozzle of the improvement. The nozzle is of' a particular and peculiar formation, the same comprising an inner tubular portion 10 threadedly attached to the tube 6. From the portion 10 the nozzle is flared outwardly and from thence rounded, as at 11. The outer face of the nozzle is concaved, as at 12. When screwed home the shoulder provided by the inner wall of the rounded portion 11 of the nozzle contacts the effluent tube, the tube also surrounding the straight portion 13 of the said nozzle inward of its rounded edge, and in this manner the tube 8 is effectively sustainedV in position.

Arranged for frictional engagement with an annular bead 8 on t-he tube 8 and with the bead 2 of the base 1 there is a rubber tubular occluding plug 1l of substantially conical formation. The reduced end forming the mouth of the member 111 is thickened and is provided with an inner groove'15 to receive the bead 8. The Iopposite widened end of the member 14 is `formed with an in wardly directed lip 16 for frictional engagement with the bead 2 of the base 1.

The base 1 is provided, adjacent to one of its edges with an outlet nipple 17, and to this nipple a suitable hose is designed to be connected.

In the showing of Figure 1 of the draw ings, three Series of openings 9 in the tube 8 are disposed between the occluding tube and the nozzle and these openings pass through the walls of longitudinal grooves 1S in the said` tube 8 so that the outflowing fluid will be positively directed into the tube and through the inner series of openings 9 near the inner end of the said tube and inte| the base.

The nozzle 12, at its mentioned rounded corner 11 is provided with any desired number of radially disposed series of openings i 19, so that the injected fluid will spray the afflicted parts. The grooves 18 in the occluding tube 8 insure the entrance of the outflowing fluid into the tube 8 and inte the base and into the occluding tube or plug 14. The tube let is constructed of soft rubber so that the saine will not infiict injury. The parts constituting the improvement are separably associated so that the metal elements thereof may be sterilized in boiling water, while the rubber occluding tube may be readily cleaned7 and it is thought that the foregoing description7 when taken in connection with .the drawing, will fully set forth the construction and advantages of the syringe.

Having described claim l. In a vaginal syringe, a cup-shaped base having its outer widened end lipped and its inner portion formed with a 'central opening surrounded by a bossVa bulb carrying nipple screwed in the opening, an inthe invention, I

fluent tube screwed in the nipple and ezi-y tending therefrom, an apertured effluent tube surrounding the influent tube and the boss in the base, a` nozzle having a.V reduced port-ion screwed on the outer end of the influent tube and having a rounded apertured corner contactable with the outer end of the efliuenttube, said nozzleh'aving its outer end concaved, a substantially cone-shaped'hollow relastic occluding tube fricti'onally engaging the effluent tube and having a widened lipped portion to engage the bead of the base, and said base having an outlet nipple.

2. In a vaginal syringe, a cup-shaped bast having its outer widened end lipped and its inner portion formed with a central depression `surrounded by a boss, a bulb carrying nipple screwed through the boss, an influent tube screwed in the nipple and extending therefrom, an apertured el'liucnt tube surrounding vthe influent tube and arranged over the boss and in the depression in the base, a nozzle having a reduced portion screwed on the outer end of the infiuent tube and having a rounded apertured corner contactable with the outer end of the effluent tube, Said nozzle having its outer end coneaved, a substantiallyv cone-shaped hollow elastic 'occluding tube frictionally engaging the effluent tube :and having a widened lipped' portion to engage the bead of the base, said base having an outlet nipple, and saidl effluent tube grooves which are apertured'and which are partly enclosed by the occluding tube.

In testimony whereof I affix iny signature.
